Embodiment Construction
[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0019] The single-point quantitative fluorescence analysis uses a fixed excitation wavelength (254nm) and a fixed emission wavelength (320nm) for fluorescence testing, while the two-dimensional quantitative fluorescence analysis is based on the working principle of the single-point quantitative fluorescence logging instrument. , change the emission wavelength from the original fixed 320nm light wave to 260-800nm for wavelength scanning, and give the two-dimensional fluorescence map of each scan (the abscissa is the emission wavelength, and the ordinate is the fluorescence intensity of the rock sample). Similar to two-dimensional quantitative fluorescence analysis, three-dimensional quantitative fluorescence also uses spectroscopic technology for excitation wavelengths. When the sample is irradiated with different wavelengths of excitation light...
